1. How many mLs of 0.560M NiCl₂ (FW=129.606) solution are required to react with 15.00 mL of 0.808M AgC₂H₃O₂ (FW=166.912) solution?

2AgC₂H₃O₂ _(aq) + NiCl_2(aq) → 2AgCl_(s) + Ni(C₂H₃O₂)_{2 (aq)}

2. A mixture of He and O₂ is placed in a 4.00 L flask at 32 °C. The partial pressure of the He is 2.7 atm and the partial pressure of the O₂ is 1.4 atm. What is the mole fraction of O₂?
